Mobile applications are developed in different platforms for different operating system such as android, ios, windows, etc. Each operating system includes a different kind of guidelines in a different format based on an operating platform. A mobile application is developed to adapt to a user environment which is nothing but a computing device e.g. smartphones. The mobile application developers are needed to develop an application in a domain-specific to the user environment. Mostly, usability guidelines in the domain-specific mobile applications are unique and the domain-specific in implementation. Every mobile application developer is unclear during these kinds of implementations. It is difficult to validate and map these kinds of domain-specific guidelines.

The mobile application developers are transforming the usability problem into usability code pattern. They are many design patterns limited for User Interface (UI) design and they are considered as the usability code patterns. Generally, the usability code patterns are a template to the developers to create or alternate the usability guidelines. The usability guidelines are structured by using respective usability code patterns. The codes generally exist in the respective mobile application development toolkit. The usability code patterns are used to evaluate the usability guidelines to understand the level of automation required by the computing device.
